(Cl. 229-28) This invention refers to improved cardboard packings of the type in which the interior of the packing is subdivided into a number of cells confined by soft and pliable walls and intended to receive fragile goods, such as glass-ware, china, etc. r

The principal object of the invention is to provide a cardboard packing of the type referred to which is in the form of inset means adapted to be placed in an outer casing to form a safe and shock-proof packing for fragile goods, such that said packing may endure when subjected to heavy shocks and when dropped from high levels without breaking the goods enclosed in the packing.

Another object of the invention is to provide a cardboard packing of the type referred to which may be composed of a minimum of separate flat elements, so that the unused packings may be stored in a minimum of space but readily and quickly assembled and fixed for use.

Another object of the invention is to provide a cardboard packing of' the type referred to, in which the individual cells are confined by walls including soft and pliable curved or wave-shaped portions conforming to the fragile goods to be enclosed therein, and further include partitions provided transversely of said curved or Waveshaped wall portions. I

Another object of the present invention is to provide a cardboard packing of the type referred.

to in which the subdivision of the interior space thereof into a number of individual cells is effected by means of a sinuous strip of cardboard and a number of parallel supporting strips extending transversely of the Wave sections of said sinuous strip and serving to support said sinuous strip and lock the wave sections thereof in permanent positions.

Another object of the invention is to provide a cardboard packing of the type referred to 1n which the subdivision of the interior space thereof into a number of individual cells is elfected by means of a sinuous strip of cardboard and a number of edgewise erected parallel supporting strips extending transversely of the wave sections of said sinuous strip and engaging incisions in said sinuous strip to support the latter and maintain the shape thereof, the wave sections forming soft and pliable wall portions of the cells capable of resiliently supporting the fragile goods contained in said cells.

A still further object is to provide a cardboard packing of the type referred to in which the subdivision of the interior space thereof into a numher of individual cells is effected by means of a sinuous strip of cardboard and a supporting structure, comprising a box having a bottom, side walls and end walls, said side walls forming parallel supporting strips for said sinuous strip, and further comprising a number of additional supporting strips for said sinuous strip provided in said box parallel with said side walls, all of said supporting strips serving to support said sinuous strip transversely of the wave sections and to maintain the shape thereof. Preferably, said additional supporting strips may be in the form of flap portions integral with the bottom of said box andformed by incisions in said bottom and bent up along folding lines parallel with said side walls. Alternatively, the additional supporting strips may be in the form of loose strips inserted in edgewise erected position in the box parallel with the side walls thereof.

A further object of the invention is to provide a cardboard packing of the type referred to in which the subdivision of the interior space thereof into a number of individual cells is effected by means of a sinuous strip having longitudinal incisions and a number of edgewise erected parallel supporting strips extending transversely of the wave sections of said sinuous strip and having projections which engage said incisions to support the sinuous strip and maintain the shape thereof by causing the Wave sec tions thereof to rest on the lateral edges of said projections.

A further object of the invention is to provide a cardboard packing of the type referred to in which the subdivision of the interior space thereof into a number of individual cellsis effected by means of a sinuous strip of cardboard having a number of cylindrical wave sections conforming to the fragile goods to be stored therein, and further by means of a number of edgewise erected supporting strips extending transversely of said Wave sections and having projections which engage longitudinal incisions in said sinuous strip to support the latter and maintain the shape thereof, the lateral edges of said projections being directed as tangents of an are from a common elevated point so as to cause the sinuous strip to rest on said lateral edges along straight prismatic portions. The cylindrical Wave portions of said strip will form a comtinuation of said prismatic portions and have said are as a cross-sectional curve, and the projections on the supporting strips will form partitionsin the rooms definedjbythe wave sections of the sinuous strip; 1

Two embodiments of the cardboard packing according to the invention are shown in the accompanying drawings, in which:

Figs. 1 and 2 show the sinuous strip and the support for the same in the form they have in the finished inset means according to the one embodiment;

Fig. 3 shows the sinuous strip in flattened condition; and

Fig. 4 shows in flattened condition a continuous cardboard blank forming the said support;

Fig. 5 shows the assembled packing as seen from above; and

Fig. 6 shows a section on the line VIVI in Fig. 5;

Fig. 7 shows the sinuous strip according to the other embodiment bent up in the form it has in the finished inset means;

Fig. 8 shows the same in flattened condition;

Fig. 9 shows in flattened condition a cardboard blank forming the support for this sinuous strip;

Fig. 10 is a plan view of a detachable strip as sociated with the support in Fig. 9.

In the embodiment shown in Figs. 1 to 6, the packing consists of two parts, to wit the sinuous strip shown in Figs. 1 and 3 and the support for the same shown in Figs. 2 and 4.

The sinuous strip consists of an elongated strip I of cardboard having longitudinal, parallel incisions 2, 3 and 4. It is further provided with end flaps 5, having transverse folding lines 6, and contiguous transverse folding lines 1 as well as transverse folding lines 8 which in the embodi ment shown divide the sinuous strip into three parts each of which is adapted to form a wave section receiving the goods, as shown in Fig. 1.

The end flaps 5 have locking flaps 9 by means of which the sinuous strip may be locked to the support for the same.

The cardboard blank I is substantially rectangular and provided with folding lines so that it may be bent up in the known manner to form a box-like support with a bottom ll, side walls i2 and end walls I3. The side walls have cut out portions i l and incisions l5, and the bottom H has cutting lines [6 forming a corresponding figure. In the bottom there are further two folding lines ll about which those parts of the bottom which are cut loose along the cutting lines l8 may be bent up so as to form supporting flaps or strips l8 located intermediate the side walls [2 and having cut-out portions similar to those of the side walls l2, as shown in Fig. 4. On those parts of the bottom il remaining after cutting out and bending up of the strips iii the pointed tongues may be removed by stamping so that they'cannot get stuck in other objects When storing the packings on shelves etc. A narrow border Ila of the bottom is maintained next to the side walls l2 and contributes to the reinforcement and holding together of the support. The end flaps have incisions l9 into which the locking flaps 9 on the sinuous strip may be inserted.

The projections 20 formed in the side walls l2 by the cut-out portions 14 and the incisions have laterally projecting subsidiary projections 2 I to lock the wave sections. At the bottom of the cut-out portions [4 there are formed small projections 14a serving to space apart the wave sections.

The packing is assembled in the followin manner. The cardboard blank it is bent up in the manner described. The sinuous strip I is then deposited on the support formed by the cardboard blank [0 first at the one end and is attached thereto in the following manner. First the projections 2!] are passed through the incisions 2 and the locking projections 2i are inserted in the incisions 4 to the left in Figs. 4 and 3,,respectively. Hereby the outermost portion la at the ends of the sinuous strip I engages in the incisions 15 to the left in Fig. 4. Then the projections 22 formed by the cut-out portions in the strips [8 are passed through the incisions 3. Next the projections 20 are passed through the incisions 2 to the right in Figs. 4 and 3, respectively, whereby the outerrnost portion to at either end of the sinuous strip engages in the incisions [5 also to the left in Fig. 4. Further the locking projections 2| are inserted in the incisions d on this side also. Finally the locking flaps 9 are inserted in the incisions iii. The support is shown in dot and dash linesin Fig. 1 as seen when connected to the sinuous strip in this manner. The projections 20 and 22 have such a shape that their free ends engage the inside of the sinuous strip I, as clearly shown in Fig. 6 with reference to the projections 22 which are truncated at the top as shown at 23.- Here the sinuous strip I rests on the upper horizontal edge of the projections 2!. The lateral edges of the said projections are directed as tangents of an arc from a common elevated point. When the sinuous strip is jammed in between these projections it will conform to the shape of the arcs and assume the form of collateral wave sections having cylindrical portions connected by prismatic portions resting on the upper edges of the projections 20 and 22. The Wave sections are kept apart by the previously mentioned projections 14a. The folding lines 1 ensure that the sinuous strip will assume the desired shape in which it will form a succession of cells consisting of cylindrical wave portion hanging on the inclined lateral edges of the projections which are not otherwise supported by the supporting portions, so that goods placed in these cylindrical wave portions, e. g. glasses 24, as shown in Fig. 5, will so to speak be suspended in the cylindrical wave portions thus formed, and consequently be well protected against the transmission of pressure and shocks from the outside of the packing. To prevent deformationrof the packing due to pressure on the outside, the width of the sinuous strip is adjusted so that the portions 25 of the sinuous strip disposed outside the incisions 2 and 4 will abut againt the inside of the outer casing in which the packing is to be placed, so that the latter will securely remain in place. Consequently, pressure exerted on the outer packing from the outside will rapidly be distributed all over the support and will not be absorbed by a limited portion thereof, so that considerable deformation of the packing and transmission of shocks to the goods packed areavoided.

In the embodiment shown in Figs. 1-6, the packing comprises six cells formed by subdividins each of the three wave sections of the sinuous strip into two cells by means of the supporting flaps I8, but the packing may easily be constructedwith fewer or more cells according to the number of goods to be packed by varying the number of Wave sections formed by the sinuous strip, and/or by varying the number of cells into which each wave section is subdivided.

Such a modified embodiment is shown in Figs. 7-10. In this case each of the three Wave sections of the sinuous strip 26 is subdivided into four portions by longitudinal, parallel incisions '21 and 28, so that the packing 6 comprises twelve cells suitable for packing e. g. china cups. Otherwise the strip 26 is provided with incisions, folding lines and flaps corresponding to those of the strip I in Fig. 3. In front of each of the said fouriportions of each wave section of the strip 26 there is cut out a flap 29 to be pressed inwardly to accommodate the ear of the cup so as to well protect the same. i

The cardboard blank 3| (Fig. 9) forming the support for the sinuous strip is provided with side walls and end walls of exactly the same construction as in Fig. 4. However, in the embodiment according to Fig. 9 there are provided detachable supporting strips 32, shown in Fig. 10, instead of the supporting flaps I8 in Fig. 4 stamped out of the bottom of the cardboard blank. These are stamped pieces of cardboard of thick resilient material and are provided with projections 33.

The packing is assembled in the same manner as previously described. The detachable supporting strips 32 are inserted at the same time as the sinuous strip 26 is placed on the support 3|. The packing is afterwards held together in the same manner as in the previous embodiment.
